Removable seat



Patented Oct. 13, 1931 v UNITED STATES REMOVABLE SEAT Application led January 6, 1931. Serial No. 506,881.

The present invention relates to removable and replaceable seats adapted for use in motor vehicles, chairs, benches and similar d articles of furniture.

It is the purpose of the present invention to provide a removable seat which may be readily employed in conjunction with the usual chair or automobile seat which is exceedingly comfortable and enables ,the use of the chair or automobile seat .for long periods of time with a minimum of fatigue. With this underlying thought in mind I have developed a removable seat of skeleton formation, consisting essentially of spaced tubes of generally round or rounded cross-section, extending in approximate parallelism lengthwise of the seat and downwardly at the front portion of the seat to form a depending apron which merges into the seat portion proper by a wellrounded curve Ifto avoid abrupt corners or angles. rThe tubes are spaced in sufficiently close proximity to afford proper support for the body, arid due to the lengthwise direction and the freedom from cross-bracing or transverse supports which come in contact with the body, the entire supporting area of the seat throughout the extent of the legs down to the knees extends generally in the direction of the blood conduits in the legs, and is entirely free from any cross-bracing or similar expedient which in any way tends to cut o'. or restrict the circulation of blood through the lower limbs. In this respect my new seat is markedly different from any.

' form of cushion with which I am familiar.

In all types of seats at present in use, Whether hard or soft, there is a tendency more or less pronounced to cut ol' and interfere with the circulation throughout the area of the front edge of the seat or cushion. Obviously this tendency to restriction of circulation is more pronounced in a hard seat or bench than in a relatively softer cushion. On the other hand, it is sufficiently pronounced even with a soft cushion which must have a reasonably firm supporting edge to substantially restrict circulation and cause fatigue after continued periods of use.

In addition to the seating function created by the spaced, rounded supports extending lengthwise of the legs, I further promote comfort by providing the supporting members in the form of hollow tubes which are in'free communication with one another-by a connection with a communicating tube connected therewith'. This communicatingtube and the inter-connected parallel supporting vtubes through a proper arrangement of oriicial openings tend to promote a circulation of air through the interior of the tubes, hav- 6o mg for its particular purpose the maintenance of a cool seat and the removal of body heat from the seat, particularly in warm weather. v

In the accompanying drawings illustrating the preferred form of the invention, Fig. 1 represents a perspective of my improved form of removable seatsuperimposed on a cushion, such as an automobile cushion; and

Figs. 2 and 3 are respectively transverse and longitudinal sections throughl the seat on the lines 2-2 and 3--3 of Fig. 1, illustrating its features of construction.

The seat shown in the illustrated embodiment of the invention comprisesessentially a tubular outer frame portion, indicated generally at 10, which may have a rounded rear portion 12, and has downwardly curved and depending ends 14 atthe front portion con- 8oI 4 nected byl a transverse tubular member 16. As indicated, the main supporting frame may be formed of a single. tube, bent or other- -wise formed into the requisite shape and con-- nected to the cross tube 16 by a suitable form 85 of welding or equivalent means of bonding. The frame 10 determines the general contour of the seat, but ordinarily is of sufficient width and length to avoid direct contact with the body of the user. l
